CCL2 and Insulin resistance: Serum asprosin concentrations were positively correlated with adiposity-related parameters (BMI and waist circumference, P < 0.01), an adverse lipid profile (increased TG and decreased HDL-C, P < 0.01), parameters of blood glucose (FPG and 2h-PG, P < 0.01), insulin resistance indices (FIns and HOMA-IR, P < 0.01), and inflammatory markers (MCP-1 and IL-6, P < 0.01) (Table 2).
